It has been said that there is no such thing as a sustainable strategic advantage. Do you agree? Why or why not?

Yes, it is very much rightly said that there is no such thing as sustainable competitive advantage. The main logic and philosophy behind my reasoning is that in today's world, products, designs, working processes, organizational secrets can easily be imitated and copied. If any organization succeeds in attaining it, then after some years and time it can still be vulnerable to be copied. For example, before fb, there were many other social networking sites were there, but now they are nowhere. Same could be the case with fb, which might take years but still it is not something impossible to achieve by anyone. Nokia, once was the market leader in the phone industry but then it lost the entire game to Apple and Samsung.

I would say that if the investor has $60,000 to invest in two stocks and is planning to invest $50,000 in one stock, and the balance $10,000 in another, then the maximum stocks to be invested in would of necessity be two .
